I'm seeing a problem where the cart in the header randomly resets to £0.00 and 0 items.
If I view the off-canvas cart, I can see the items. When I close it, the header still says 0.00 and 0
If I then go to another page, it displays correctly. For a while. But then goes again.
If, when it has gone to £0.00 and 0, I add an item, when I close the off-canvas cart and it returns to the page I was on, it also displays correctly. For a while. But then goes again.
I am not closing the tab or the browser.
This is happening using responsive theme as well as my own based on it, in development mode, with no logged in user.
Opcache is enabled but regardless, it shouldn't cause this issue surely?
Does anyone have any ideas please?
Using 5.51 but think it was happening before that.
